Description

L-Glutathione is a vital tripeptide composed of glutamic acid, cysteine, and glycine, serving as a master antioxidant and detoxifying agent in biological systems. Its primary commercial value lies in its ability to combat oxidative stress, support cellular health, and maintain redox balance. This essential compound is in high demand across the pharmaceutical, nutraceutical, cosmetic, and food industries for applications ranging from active pharmaceutical ingredients and dietary supplements to skin-whitening agents and food preservatives.

Application

• Pharmaceutical Active Ingredient: Used in formulations for liver protection, detoxification therapies, and treatments for conditions like Parkinson's disease and cataracts.
• Dietary Supplements & Nutraceuticals: A key ingredient in capsules, tablets, and powders aimed at boosting immunity, enhancing athletic performance, and promoting anti-aging.
• Cosmetics & Skincare: Incorporated into creams, serums, and lotions for its skin-brightening, anti-aging, and antioxidant properties to reduce hyperpigmentation and wrinkles.
• Food & Beverage Industry: Utilized as a natural preservative and antioxidant to prevent spoilage and maintain flavor and color in food products.
• Research & Biochemical Reagents: Serves as a critical reagent in cell culture media, enzymatic studies, and biochemical research investigating oxidative stress pathways.
• Animal Feed Additives: Added to feed to improve animal health, growth performance, and meat quality by enhancing antioxidant status.

Quality Control

Our L-Glutathione is manufactured under strict quality management systems. We offer various grades, including Pharmaceutical (USP/EP), Food (FCC), and high-purity Reagent grades, each meeting stringent specifications for identity, purity, and safety. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and microbiological data to ensure compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider using an inert atmosphere (e.g., nitrogen or argon) in the headspace of the container to maximize stability and shelf life.
